Find Topography Data

The map below shows the extent of datasets currently available via OpenTopography. These topographic data are available in a range of formats depending upon who acquired the data and what product types were delivered. The classes of data types available include: lidar point cloud data, standard digital elevation models (DEMs) and Google Earth imagery files. For lidar point cloud data, web-based tools are also available to process these data into custom DEMs.

Also discoverable are extents, metadata and links to access datasets hosted by other online lidar data centers.

Navigation of the Google Map below is performed using the zoom bar and navigation arrows in the upper left hand corner. To make a selection, click the "SELECT A REGION" button and draw a box on the map that corresponds to the portion of the lidar dataset that you are interested in. Results will appear below the map. Available data are shown as dots or polygons on the map color coded by data center.
